Physics Unit 1

QuestionAnswer
Speed scalar quantity that refers to how fast something is moving
Scalar only magnitude, no direction
Speed Equation speed = distance / time
Distance the total length measure between objects without regard for direction
Velocity vector quantity that refers to how fast something is moving
Vector both direction & magnitude (ex: -5mph or 5mph to the left)
Velocity Equation velocity = displacement / time
Displacement how far you are regardless of how you got there
Displacement Equation Δt = xf - xo
Average Velocity Equation v = Δx / Δt or v = (x2-x1) / (t2-t1)
Position Equation x = xo + v(t)
Models Of Motion equation, graph, table, & dot diagram

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
